Koscheck out of UFC 109, Mike Swick steps in

UFC welterweight star Josh Koscheck has withdrawn from his UFC 109 rematch against Paulo Thiago due to an undisclosed injury. Koscheck’s American Kickboxing Academy teammate Mike Swick will replace him in the bout.

Koscheck last appeared at UFC 106 in November, where he defeated Anthony Johnson in the most high-profile appearance of his career. Koscheck is believed to be on a short list of contenders to Georges St. Pierre’s welterweight championship throne.

A source close to Koscheck told Brawl Sports on Monday night that Koscheck’s injury isn’t serious, and he’ll be able to resume training in mid-January.
